How to delete child domain in V 2.0

Hello,
I have searched the way to delete child domains but in V 2.0 there is no one option shows to delete child domains.
Can someone tell me how can I do it?

Regards,

To delete a child domain in v2.0 or newer, go in to manage the parent domain.

https://192.168.100.10:8090/websites/example.com

Replace 192.168.100.10 with your VPS/Dedicated server IP Address, and example.com with your parent domain.

Scroll down to the Domains sections and click LIST DOMAINS.

You will see the “Delete” button there.
